COMEUTATOR CARD HOLDER Filed Jan. '7, 192g gmc/Mm Patented June 24, 1930 UNITED STATES coMPU'rA'ron CARD vHomann Application filed January 7, 1929. Serial No; 330,945.

The object of this invent-ion is to provide a novel card holder for use on computators and other devices.

It is within the province of the disclosure to improve generally and to enhance the utility of devices of that type to which the invention appertains.

lVith the above and other objects in view, which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that, within the scope of what is claimed, changes in the precise embodiment of the invention shown can be made without departing from the spirit of the invention.

In the accompanying drawings Figure 1 shows in elevation, a gasoline dispensing tank equipped with the device forming the subject matter of thisy application;

Figure 2 is a fragmental longitudinal sectional view showing how the card holder is mounted in place;

Figure 3 is a front elevation showing a part of the card holder, parts being broken away; v l Figure 4 is a transverse section of the structure depicted in Figure 3;

Figure 5 is an elevation showing a modification, parts being broken away;

. Figure 6 is a transverse section of the device shown in Figure 5. Y Y

Although the structurel forming the subject matter of this application may be lput to many uses, it will be supposed, in order to avoid unnecessary prolixity in the description, that the device claimed'is-to be'used in connection with a measuring tank for fuel, and, more specifically, a gasoline tank.

In'the drawings, the numeral 1 marks a tank including a cylindrical body 2, generally made of glass. The body 2 is surmounted by a cap 3 having av depending flange 4, the lower portion of which is spaced apart from the body 2, as shown in Figure2`. The tank 1 is supported on a base 5 having an upstanding flange 6, the upper edge of which is spaced from the body 2 in a way which will be understood readily when the flange 4 .of Figure 2 is examined. Y

In carrying 'out the invention, there is provided a card holder which, as a whole, is designated by the numeral 7. holder 7 is made of metal having some resiliency, and includesl a base plate 8 4provided The card f along one edge with an overhanging first flange 9, and along its opposite edge with an S-shaped flange 10, comprisingV an inner .trough-shaped socket 11, and an'voutel trough-shaped socket 12. Into Y the louter troughfshaped socket. 12 are inserted the butt ends of a plurality of triangular indii eating fingers 14 and 15, the lingers 14 and 15 being retained in the socket 11 with a strong vfrictionalholding,but not so strongly but that they can be `adjusted longitudinally of the card holderv 7, as occasion may demand.

.The card y16 is removably inserted, endwise, g

within thel flangel 6 and within the: inner socket 11, the card being marked at 17 with the pricey of whole gallons of gasoline,'and being marked at 18 with the price of frac tional parts of a` gallon.

The holder 7 has some resiliency, and it may be bowed, as shown' at 19 in Figure 2,

'to find out how man* gallons'thereare in the tank, he can, at the same time, ascertain fthe-price of the number of gallons to be disrlhus, noting the point at which the pensed. reference numeral 211s applied'in Figurey 1, if two gallons are to'y be vdrawn off, the cost, as shown at 22, will be $.44, the cost of the gasoline being` read olf the card 16 in the holder 7.V In order to'avoid mistakes in read- "f ing olf the price of the gasoline, recourse isY had to the indicating fingers 14 and 15.

All tanks are not ofthe same diameter,

and,.therefore, the distance between the caliy brations on the index strip 20 will vary. Al-

vthereby to insert the ends of the 'card holder l l within the flanges 6 and 4, the card holder,

Lin

though this is so, it is not necessary to have a different card holder 7 for every difference in the diameter of the tank. One card holder will suiiice since the indicating fingers 14 and 15 can be adjustedl longitudinally of the card holder, to coincide with the calibrations ot the strip 20. i

There may be, as `many of the vcards -16 as is desired, so that the machine may be adapted quickly for changes in price, it being necessary merely'to slip one card into the holder 7 in place of another, when the market Y changes. Y

In Figures 5 and 6 parts heieinbe-fore dcscribed have been designated by numerals previously used With the sufiiX a.

In the form shown in Figures 5. and 6,the

Vou-ter'vvalloi the outer socket 12a has-a rear- Wardly .inclinednlip' 23 which overhangs the end of the innersocket 11a. The index lingers 24 areofsetslightly, as at 25, to fit behind the lip- 23, the construction being such that an additionalhold onthe-fingers 24 is provided.

vAt their inner ends, the'fingers 14C are slit longitudinally, as at 26, to form tongues 27,

vtwo of VWhich bear against the inner Wall .ofthe outer-socket 12a,.and the third of Which (the middle one) bearsagainst theinner Wall of the socket 11a; The. tongues 27 are resilient and aid in holding the indicating :fingers inl any position to Which they may have been adjusted, as andi for the purpose hereinbe'fore set forth` in connection with the `fingers 141-15 of Figure 3.

The construction of thedevice is suchthat the 'liquid level in the vtankly indicates'on the strip or scale 20, the amount of liquid to be dispensed, and upon-the scale 1.8-1?, the priceof the liquid. n Y

'I claim Y Vl. A' card holder including a base plate `provided along one edge With a iirst flange.,

and along its opposite edge with ans-shaped flange forming inner and outer sockets, a Card having calibrations and removably mounted in the first flange and in the inner socket, and .Y anhindicating finger cooperating With the calibrations, the indicatingv finger being mounted in the outer socket for adjustment longitudinally of the card holder.

2. A device of `the class described, con structed as set forth in `claim 1, and further characterized by the fact that the indicating A llingers are slit Vat their, inner ends to form tongues .bear-ing, respectively, against the outer Wall of the outer socket, and against the inner Wall of the outer socket.

In testimony that l claim the ioregoing as myown, I have hereto aiiixed my signature.
